Abstract: 962,401. Blasting. CLERK, KING, POYNTER & CO. Ltd. June 19, 1963 [May 11, 1962], No. 18232/62. Heading B3D. A machine for dry cleaning eggs comprises a conveyer including egg-rotating means, a rotary grit thrower whose efflux is directed at the side of the conveyer and is arranged to bombard several eggs simultaneously, and an air compressor whose output operates an air lift transporting grit from a hopper to the eye of the thrower. A cleaning machine is supported upon a three-legged table having a knee-hole apron at which an operator sits, loading and discharge shoots 1, 2 being sited at opposite sides of the operator's station. Parallel spindles 3, 4 extending substantially from one side of the machine to the other are driven, in the same direction, by an electric motor 6 to rotate an average sized egg resting on the spindles at about 30 r.p.m. about its long axis. A beam 5 having dishes to hold eleven eggs and located between and below the spindles 3, 4 is mounted on a parallel linkage system 7, 8, 9 and moved through rollers 10, 11 bearing on cam-plates driven by an electric motor 12 so that every three seconds the beam lifts, moves forward three inches and descends, whereby all the eggs resting on the spindles 3, 4 are advanced by three inches. Labyrinth locks shroud the inlet and outlet of a work chamber. In the rearward position of the beam 5 one dish is at the loading station from the inlet shoot, one is in each of the labyrinth locks and eight are within the work chamber; in the forward position of the beam, one dish is brought to the off-loading position at the outlet shoot. A grit hopper 13 has a hinged cover 14 carrying an electric motor 15 driving a centrifugal compressor 18 and a rotary grit thrower 19. The outlet of the compressor casing is connected by a flexible pipe 20 to a chamber 21 at the base of the hopper containing the inlet of a Venturi 22. The latter is connected to an air lift tube 23 terminating in a discharge head 24. Grit inlet ports in the tube 23 are closed by a sliding tubular gate 25 when the machine is idle but are opened by air pressure on the gate when the machine is operational. The compressor derives its suction from within the work chamber and hopper, so that the chamber is maintained at sub-atmospheric pressure. The compressor has a centrifuge bleed for dirt and dust which pass to atmosphere through a filter. In a modification, Fig. 4, the hopper 13a has an outlet 30 and a Venturi constriction 22a is provided on the air inlet side of an air-lift tube 23a leading to a discharge head 24a.

Title: Potentiometric titration method and apparatus therefor
IPC: G01N31/16
Filed: 1973-04-16
Abstract: 1421223 Automatic titration E I DU PONT DE NEMOURS & CO 16 April 1973 18292/73 Heading G1N The end-point of a potentiometric titration is determined automatically using an electronic computer which generates a representation of the actual end-point of the titration. In the determination of amine end groups in a nylon polymer by titration with a perchloric acid titrant a solution of the specimen is brought into contact with an electrode connected to a digital pH meter and an automatic burette. After the pH reading has become stable the stepping motor of the burette is controlled d digital computer via an interface to deliver 250 Ál of titrant. After waiting 10 seconds the pH meter is read by the computer and the initial slope value of the titration (#m V/250 Ál) is calculated by the computer. Further additions of 250 Ál of titrant are added and the same procedure carried out by the computer until the slope value reaches 0À06. At this point the size of the increments is reduced to 80 Ál and the titration monitored until the slope-value reaches 0.12 when once again the increments are reduced to 27À3 Ál. During this part of the titration the computer is programmed to count the number of seconds required until the meter output is stable and then wait for an equal length of time before reading the meter. When the slope-value reaches 0À35 the increments are finally reduced to 9À74 Ál and titration continued on through the end-point, indicated by a decrease in the change in meter output per increment. The computer orders five more incremental additions after the end-point before completing the titration. The last thirteen values of meter output (mVs) and corresponding values of total titrant volume added are stored in the computer which then makes a least squares analysis to fit the stored data to a cubic equation of the form Y = A + BX + CX<SP>2</SP> + DX<SP>3</SP> where Y is the millivolt reading and X is the volume of titrant. The end-point X end (point of maximum slope) is then determined from the equation Xend = -C/3D. Alternatively instead of the cubic equation one of the form Y = C Cot<SP>-1</SP> [(x-a)/b] may be used using the method of successive approximations. The computer is also fed with the specimen weight and moisture content so as to calculate the concentration of amine end-points.

A device for dividing printing rollers circumferentially into equal parts comprises a composite ring structure, which may be placed around the roller, having three jaws guided in radial slots in one face thereof and movable simultaneously to equal extents to engage or release the roller by turning a ring incorporated in the composite ring structure, the other face of the ring structure having radial bars thereon, each having a side face serving to guide a member for marking the surface of the roller, the radial bars being spaced so that the surface can be divided by markings into any desired number of equal parts. As shown, a ring e is rotatable in a recess between rings band c, which are fastened together. Three evenly spaced clamping jaws h slide in grooves in ring b, and engage spiral grooves in ring e so that, when ring e is rotated by means of handles f the rings band c being held by a handle i) jaws h move together to clamp the device to roller a, or to release it. Ring c carries radial bars such as k, arranged in groups for dividing the roller surface into 2, 3, 4 or 5 equal parts. A straight edge o is laid against each bar of the chosen group in turn, so as to abut against the roller a to mark its surface. When one end of the roller has been marked, a line is drawn through one mark parallel to the roller axis, and the device is moved to the other end to make a second set of marks, the first of which coincides with the line.
